  • Page 33: Connecting Hosts

    Use the set host-port-mode CLI command to set the host interface protocol for MSA 2040 SAN host ports using qualified SFP options. MSA 2040 SAN models ship with host ports configured for FC. When connecting host ports to iSCSI hosts, you must use the CLI (not the SMU) to specify which ports will use iSCSI.

  • Page 34: Fibre Channel Protocol

    Each controller module provides four host ports designed for use with an FC SFP supporting data rates up to 16 Gbit/s. When configured with FC SFPs, MSA 2040 SAN controller enclosures can also be cabled to support the optionally-licensed Remote Snap replication feature via the FC ports.

    Remote Snap replication feature. To connect the MSA 2040 SAN controller to a server or switch—using the 1 Gb SFPs in controller ports—select the appropriate qualified RJ-45 SFP option (see the QuickSpecs). Such cables are also used for connecting a local storage system to a remote storage system via a switch, to facilitate use of the optional Remote Snap replication feature.

    Host ports and replication MSA 2040 SAN controller modules can use qualified SFP options of the same type, or they can use a combination of qualified SFP options supporting different interface protocols. If you use a combination of different protocols, then host ports 1 and 2 are set to FC (either both16 Gbit/s or both 8 Gbit/s), and host ports 3 and 4 must be set to iSCSI (either both 10GbE or both 1 Gb).
